标准摘要
[中文适用范围]： IEC 62321的第3-2部分规定了通过使用燃烧离子色谱分析技术对聚合物和电子产品中均质材料中的总溴（Br）进行筛选分析。本部分IEC 62321规定了使用燃烧离子色谱（C-IC）对聚合物和电子产品中的氟、氯和溴进行筛选分析。碘的C-IC筛选分析程序见附录D。本测试方法已在ABS（丙烯腈-丁二烯-苯乙烯）、EMC（环氧模塑化合物）、PE（聚乙烯）和PC（聚碳酸酯）中进行了评估，浓度范围如表1、表2和表3所示。使用此方法对其他类型材料或超出指定浓度范围的材料尚未评估。本标准不旨在解决与其使用相关的所有安全问题（如有）。使用本标准的用户有责任在使用前建立适当的安全和健康实践，并确定法规限制的适用性。本标准主要用于技术委员会根据IEC指南108中规定的原则制定标准时使用。 [外文原描述]： IEC 62321-3-2:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62321-3-2:2020 specifies the screening analysis of fluorine, chlorine and bromine in polymers and electronics using combustion-ion chromatography (C-IC). IEC 62321-3-2:2020 cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) In the previous edition, a screening test method for bromine (Br) content only was provided. In this edition, a screening test method by C-IC for fluorine (F), chlorine (Cl) and bromine (Br) has been added to the normative part of the document. b) A screening test method by C-IC for iodine (I) has been added in Annex D (informative). It has the status of a horizontal standard in accordance with IEC Guide 108 .
